Do you need to choose a pump for watering your garden, but due to the variety of offers on the market, is it difficult to choose the right model? In this publication we will tell you what types of pumps there are, their characteristics, and what indicators you should pay attention to when choosing.

If country estates have a garden plot, then most likely it is used either for agricultural or for decorative and floricultural purposes. In both cases, it is impossible to do without regularly carrying out certain agricultural work. And irrigation will always be in the foreground - without effective watering, especially in dry summers, it is hardly possible to achieve a high yield, beautiful flowering flower beds or even just a lush green lawn.

Even if a water main is connected to the site, using water from it for irrigation is by no means the best solution. Firstly, it is very wasteful, and secondly, such water undergoes certain processing, including chlorination, and is not very useful for plants. For watering, it is better to use some natural source, but to use it you will need special equipment - a pump.

However, if a buyer goes to a store or accesses an online catalog unprepared, he may be faced with a host of questions that will make making the best choice extremely difficult. Pumping equipment has many faces and differs not only in technical characteristics, but also in operational capabilities. It is necessary to take into account many criteria in advance in order to choose the model that is most suitable for the existing conditions. This is what this publication is devoted to - buying a pump for watering a garden: varieties, selection, installation, basic operating rules.

We evaluate the general characteristics and capabilities of the pump

Where will the water be taken from?

It is impossible to choose the right pump if you do not decide in advance where the water for irrigation will be taken from. There can be many options here.

• The most successful “situation” is when the site has its own or a body of natural origin located in close proximity - a pond or lake, fed from underground sources or a stream and with sufficient water flow. You can irrigate from a nearby river. In any of these cases, a surface pump or a submersible (semi-submersible) drainage type may be required.

If there is an artificial reservoir on the site - a pond or swimming pool, then it can also become a source of water for irrigation. All the same, the water in it must be changed regularly, and you can combine these two operations - supply fresh water to the pool, pumping out the water that already requires replacement to the garden. True, under one condition - that no chemical reagents were used.

• Even a somewhat swampy body of water can serve as a source of water for irrigating the area, but in this case you will have to purchase a special type of drainage pump, which is designed to pump specifically dirty water.

However, such ideal conditions are quite rare. Most often you have to resort to artificially created water sources.

• For irrigation, you can use water from a well or well. For wells, both surface pumps (if the aquifer is shallow) and submersible pumps can be used. For wells where water is usually found at great depths, only special types of submersible pumps are suitable.

Taking water from wells requires special pumping equipment.

To lift water from great depths and at the same time ensure its sufficient pressure and required flow rate for further use - not any equipment can cope with this. Read how to approach it in a separate publication on our portal.

However, an important note should be made immediately. Any experienced gardener or gardener will tell you that using water directly from a well or borehole for irrigation is extremely undesirable, since such irrigation of plants can do them more harm than good. The best option is to pump the required volume for regular watering into containers installed on the plot in advance. The water will warm up within a day, get rid of the chemical compounds dissolved in it, and become quite suitable for irrigation. By the way, this approach opens up wide possibilities for the competent use of fertilizers and fertilizers with strict adherence to the recommended proportions for diluting the compositions.

To set containers, the already mentioned well or borehole pumps are used. But directly for watering, you will have to acquire a compact surface-type garden pump or special submersible models designed specifically for collecting water from containers (barrels, Eurocubes, homemade tanks, etc.).

• A good owner should not waste anything, including rainwater, which is often collected from drainage systems into garden containers. And in addition, if a competent storm drainage system is organized on the site, then a storage storm sewer can also become a source of water for irrigation. In this case, a submersible drainage pump will again become an assistant.

How are storm drains constructed?

Unfortunately, not everyone remembers about this system for draining water from the local area, or they ignore its creation in the hope that everything will somehow “resolve” by itself. Why this approach is wrong, and how to create it correctly, read in a separate article on our portal.

So, the choice of irrigation pump will primarily depend on the type of water source used.

What performance indicators and generated pressure are required?

Whatever type of pump is chosen, this unit must fully cope with the functions assigned to it.

1. Firstly, it must ensure that the required volume of water is pumped at a certain time - this is an indicator of productivity.

Calculating this parameter is not difficult at all. It is assumed that, according to existing rules, for high-quality irrigation of one square meter of land, from 3 to 6 liters of water are required (depending on local climate conditions, the characteristics of the crops grown, and the prevailing weather). It is best to calculate to the maximum - this will create a certain productivity reserve, but everyone is free to decide this issue on their own.

Of course, only the area of ​​the plot that is allocated for crops that require regular watering is taken into account. If lawn or flower beds are cultivated, their area is also taken into account.

The next value required for calculation is the time that is planned to be spent on watering the entire area. Usually this event is held in the evening, after the heat of the day and the aggressiveness of direct sunlight have subsided, so probably an hour or two will be enough.

To find the required productivity (usually denoted in technical documentation by the symbol Q), all that remains is to multiply the area of ​​the irrigated area and the rate of its irrigation, and divide the resulting value by the time allocated for irrigation.

Q = S uch × N/t

S uch – area of ​​irrigated area (m²).

N – The accepted irrigation rate is from 3 to 6 l/m² (for individual crops it may be more).

t – time allotted for watering the site.

For ease of calculation, you can use the proposed calculator. The area in it is indicated in acres - this is what many gardeners are used to.

This is not a joke or a prank. The water pump we are talking about really does not require electricity, gasoline, or anything else. It does not draw energy from the ether and does not catch free energy. With all this, it is capable of raising a column of water several times higher than the initial pressure. No deception or trickery - ordinary physics and nothing more.
Of course, if you see such a pump for the first time, then like me you may think that this is nonsense... The same as the invention of a perpetual motion machine... But no, everything is much simpler and quite easily explained. This is a 100% working model of a water pump, repeated by more than one craftsman.

Making a water pump

So, first, I will tell you how the pump works, and then its operating principle and operation in real conditions.

Design with description

This is what he looks like. Everything is made from PVC pipes.

In this case, the design looks like a straight pipe with various valves and taps, with a branch in the center of the thicker diameter pipe.
The thickest part is a buffer or receiver for accumulating and stabilizing pressure. Inlet and outlet ball valves are installed on the left and right.
I will be looking at the pump from right to left. Since the right side is the entrance for water, and the left is the exit.
In general, we realized that water is supplied to the ball valve on the right. Next comes the tee. Tee, separates the flows. It flows up to the valve, which closes when there is sufficient pressure. And the direct flow is supplied to the valve, which opens when the desired pressure is reached.
Then, the tee goes again to the receiver and to the output. Oh, and a pressure gauge, but it may not be there, it’s not that important.

Details

All parts are laid out before assembly. I use PVC pipes, they are glued with glue, but polypropylene can also be used.

Valve.

Assembly

I'm collecting. The second valve is in the middle and looks a little different. The difference between these two valves is that the brass valve will initially always be open, while the PVC valve will initially always be closed.

Assembling the buffer-receiver.

The end part of the pump.

Almost finished sample.

Let's add a pressure gauge to measure pressure during operation.

The water pump with pressure gauge is ready for testing.

Pump tests

It's time to install and test the pump. I would like to make a reservation and say that the pump does not pump water, but rather increases its pressure. What I mean is that the pump needs an initial pressure to operate.
To do this, install a pump in a small stream. Let's connect a long pipe several meters long (this is a mandatory condition) and draw water from a small hill. As a result, water will flow to the pump itself.

We place the receiver vertically, the brass valve should be in the open air.

And the pump, clicking the valves, begins to supply water above the intake level. Much higher than the level of water intake at the beginning of the pipe.

All this seems truly amazing and incredible, but there is no secret here. Such water pumps are also called hydraulic shock pumps and they work like this:
When water is supplied, it immediately rushes into the open valve.

As soon as the water gains a slight run-up, this valve will close sharply. And since the column of water in the pipe has inertia, like any physical mass, a water hammer will occur, which will create excess pressure that can open the second valve. And the water will rush into the receiver, where it will compress the air.

As soon as the excess pressure is extinguished and becomes less than the outgoing one, the middle valve will close and the upper one will open. As a result, water will again flow through the top valve.

Then the cycle repeats.
For more detailed animation, watch the video:

Such pumps can create pressure 10 times higher than the initial one! And to confirm this, watch the video:

Between the installation of the casing and the installation of pumping equipment, there is another important stage - cleaning the well from dirt that has accumulated there during the drilling period. Clay suspension, sand, impurities will remain in the source shaft, will clog filters and disable mechanisms if they are not removed in a timely manner. Let's try to find out which pump to pump the well after drilling and whether it is possible to carry out the cleaning procedure with your own hands without violating technological standards.

The drilling process disturbs the soil layers, as a result of which the rocks fall to the bottom - exactly where liquid from the aquifer subsequently begins to flow. This is a natural order, and you can’t do without construction dirt. Between the clay and sandy loam layers, water that is not crystal clear also flows; for this reason, installing a filter is a necessary condition for the functioning of the source. A certain amount of foreign impurities, like clay-sand suspension, will always affect the quality of water and be the main cause of filter clogging and mechanism failure.

To delay the repair or replacement of mesh parts, a scheduled pumping is carried out, during which the following actions occur:

• lifting crumbled soil to the surface;
• washing away dirt from the bottom of the mine;
• drainage of wastewater into a drainage ditch.

During the event, not only the lower segment of the pipe is washed, but also the layer of soil bordering the mine, so subsequently the water entering the sump becomes much cleaner and more transparent.

Professional well pumping after drilling

This is not to say that after the initial, starting “cleaning”, such a kind of general cleaning will no longer be needed. Over time, silting will occur or the fine mesh will become clogged with particles of concentrated sand suspension, and washing will be required again, but on a smaller scale. If it is not carried out for preventive purposes, the depth of the water column will decrease, the quality of the liquid will noticeably deteriorate, and the flow rate will decrease.

How long does the process take?

The cleaning time depends not only on the choice of type or power of equipment. All factors are important:

• soil type (percentage of clay and sand);
• internal diameter of the casing pipe;
• the depth at which the sump is located;
• water flow rate, etc.

The minimum period of time required for deep cleansing is approximately 12 hours, and the process must not be stopped (for this reason, pumps that require a break every 2 hours are not suitable). The signal to stop the swing is a relatively clean flow of liquid. It won't be drinkable for a few more weeks. But during this period, water can be used for technical purposes - for cleaning the site, watering the vegetable garden, garden and flower beds.

Attention! If the soil contains chalk or a large amount of clay, the rocking process lasts several days.

The two main methods – internal and external – are not always used in combination. Before deep cleaning, internal pumping is carried out to remove deposits from the pipe walls, and external pumping is necessary to completely remove clay crust from the outer sides. The casing, settling tank and sand-clay horizons adjacent to the structure are subjected to the procedure. For both types of declaying, three methods are used:

• physical (manual, using a set of special tools);
• chemical (acid-based reagents);
• hydromechanical – flushing under high pressure.

Before starting to operate country wells, the latter method is most often appropriate; it is also optimal for self-boosting. A powerful stream dissolves clay particles and washes them away, and then the heavily contaminated water is discharged out using pumping equipment. This process is familiar to everyone who has ever cleaned a well or borehole using pumps. Before pumping a well after drilling, it is necessary to select the right pump.

Discharge of a hose with dirty water into a ditch during hydromechanical pumping

Selection of pumps for pumping

Some craftsmen do not attach much importance to the choice of equipment and buy the most inexpensive vibration device, which after the procedure becomes so clogged that it must be disposed of. However, we will consider all options.

Vibrating

The principle of operation of the mechanism is simple: due to the operation of a magnetic coil inside the chamber, the pressure changes, facilitating the transfer of liquid through the filters. As a result of the movement of various parts of the device, it produces vibration, which is why it got its name. The main advantage of vibration technology is its low cost. The cost of “Rodnichkov”, “Neptune”, “Kids” is 1500-3000 rubles, that is, if it breaks down, you don’t have to deal with repairs, but buy another device. The design of the mechanism is quite simple; it requires a nearby electrical power source to operate.

Vibrating submersible pump “Baby” - for shallow mines and relatively clean water

The vibration required to pump water can play a cruel joke. A constantly running apparatus, in contact with the walls of the casing pipe, causes clay to shed, increases contamination and causes self-destruction of the well. In addition, there is a risk of the suspension breaking, so do not use a regular rope to mount the device at depth; it is better to use a strong steel cable. The device is not very powerful, which means that the cleaning process will take a long time. A heavily polluted environment will quickly clog the filters, and the rubber parts will constantly wear out, so if speed is important, stock up on several devices so that you can quickly replace them if necessary.

Vibration technology is good for prevention or routine cleaning, but is considered weak for washing out soil after drilling.

Screw

Screw-type devices operate due to the movement of a screw auger. The movement of the rotor inside the chamber displaces the media, thereby performing pumping. The performance of the mechanism depends solely on the speed of the auger. The cost of screw devices is higher than vibrating submersible analogues - from 6,000 rubles, but these are special models designed for pumping clean water. A polluted environment requires more powerful downhole equipment, the cost of which reaches 20,000 rubles.

Unlike vibrating models, screw models break much less frequently, do not cause additional contamination and do not pose a threat to the casing. For optimal operation, it is recommended to take the equipment out several times during the procedure and clean its parts.

Attention! The dimensions of a screw pump depend on its power, so when choosing a powerful device, consider the internal diameter of the casing pipe.

Self-priming screw models are not afraid of sand and are suitable for wells and boreholes with a high content of foreign impurities.

In centrifugal-type devices, water is supplied upward by rotating a wheel with blades. This is a surface mechanism, that is, it is installed in a caisson or basement of a house, and its working chamber, connected by a hose, is immersed in a sump with water. The cost of popular models “Belamos”, “Caliber”, “Zubr” - from 5,000 to 10,000 rubles. They have high productivity and do not require special maintenance; in the future they can also be used to supply water to a country house.

Using universal centrifugal pumps for irrigation (after pumping)

Disadvantages - a negative reaction to power outages and dry operation, so it is recommended to connect stabilizers and choose a model with dry-running protection. Usually, when there is sudden drying, a relay is triggered and the device automatically turns off. If you are in doubt about which pump to pump the well after drilling, choose a centrifugal device - it will work without replacement even in an environment with a large amount of impurities and sediments.

How to properly pump a well with your own hands

There are many options for carrying out the procedure; let’s consider one of the simplest and possible even for a summer resident uninitiated in the technical wisdom. We will pump out dirty water using two pumps, the vibrating “Malysh” (the most popular model for well irrigation, which is why many have it) and the centrifugal “Aquarius”. The first one will withstand even a thick mixture containing solid particles, but it cannot be used for more than 36 hours. Vibration is not the best method for a newly installed structure, as it causes additional dusting and can create sand throughout the week. Therefore, after the liquid has brightened, we remove the vibration and install a centrifugal apparatus.

Attention! Filters must be constantly in the water, so taking out all the liquid from the sump is strictly prohibited!

You can also control the liquid level by the operation of the equipment: as soon as a large number of air bubbles appear in the drain, turn off the device. A minimum of liquid leads to thickening of the medium, sticking of solid particles and complicating further cleaning, as well as breakdown of the pumping mechanism.

Pump pumping and water level control

Before pumping the well with your own hands, check the diameter of the pipe and measure the height of the water column, since for greater productivity the volume of pumped out liquid is usually controlled. We measure the flow rate of the well: multiply the diameter of the pipe by the height of the water column and divide by the filling time. We compare the result with the performance of the pump and calculate how long the equipment can operate without problems, and when critical drainage will occur. It’s even better if you make calculations before purchasing a centrifugal unit in order to choose a model that is suitable in terms of power and performance.

A timer, which most modern models are equipped with, will help you regulate the operation of the pumping apparatus. Setting it for a certain time will allow you to stop the pumping in time until the sump is completely filled.

Attention! Work must continue until perfectly clean water flows. This may take a week, two or even three - during this time the well must be operated to its maximum.

Typical rocking mistakes

A few tips will help you quickly cope with cleaning without wasting time correcting errors:

• Do not hang the working chamber of centrifugal equipment (this also applies to vibration equipment) too low, above the very bottom of the sump. Silt, clay formations and solid particles will quickly clog the filters, and you will have to remove the equipment every 15 minutes for cleaning.
• Do not place the mechanism too high, near the mirror. This way you will swing the main volume, which is relatively clean, and the main contaminants will remain at the bottom. In the future, they will enter the water intake, clog filters and the entire water supply system.
• Drain waste as far away from the mine as possible. The liquid drained near the well will re-enter the ground, seep into the pipe and wash away the clay layers, which will cause further pollution.
• Choose equipment that is suitable in terms of power and performance for the volume of water, so you will speed up the cleaning process, and in the future, preventive procedures.

When using this or that pump model, pay attention to its operation in extreme conditions (during general cleaning) and in normal mode - for lifting clean water or watering the garden.

Installation of a pump near a well

Siltation and quicksand: methods of protection

The initial pumping is just the beginning of cleaning activities, since over time the bottom and walls of the shaft will silt and the filters will become clogged with sand and clay. Subsequent maintenance is necessary both to keep the equipment in working condition and to improve the quality of water from the well. For example, the period of groundwater movement is considered stressful, when melting snow causes it to rise. Together with the liquid, both floaters (layers of sand) and harder sediments in soil layers move, as a result of which “plugs” often appear. To avoid this, you will again need a sufficiently powerful, already proven unit.

Correct installation of the filter to protect the pump from silting

There are several methods of prevention:

• intensive use (more active operation of equipment);
• cleaning from silting and sand deposits (as during rocking);
• hydraulic pressure method using a pump.

So, the main factors when choosing a pump for pumping (definitely a submersible one) remain its technical characteristics: power, productivity, long-term ability to work without interruption, versatility. In addition, it is worth considering the composition of the soil and the depth of the mine.

In the absence of public water supply networks nearby, local water sources are used for water supply. The most common and fairly reliable option is a well. Its depth depends on the occurrence of the aquifer closest to the surface and is, as a rule, 15-20 meters.

In order for the water in a well to be clean and safe, it must be properly equipped and removed from all possible sources of contamination: sewerage treatment systems, burials, cesspools, livestock farms, etc. If wastewater enters a well, it must be cleaned and disinfected.

In addition, water from a well or pond entering the house must undergo multi-stage purification. First, from large mechanical particles using mesh filters, then from sludge and various suspended matter in sedimentation or membrane filters, and finally, from microbes and bacteria using devices for additional purification and disinfection of water.

To lift water from a well, various types of pumping equipment are used, depending on the depth from which the water will have to be pumped. Water can be supplied from a natural reservoir or shallow well using a surface self-priming pump. Such a pump is designed for a maximum suction depth of 7-8 meters, provided that it is located near the source.

If the pump is installed in a house and connected to the well with a hose or pipeline, then the actual suction depth is reduced by the amount of pressure loss when pumping water through the pipe. Losses are greater in rough metal pipes of small diameter. But for wide polyethylene pipes (more expensive) they are small and, in practice, can be ignored. The self-priming pump must be constantly filled with water during operation. Before initial start-up, water is poured into it manually. To prevent it from leaking, a check valve must be installed at the beginning of the suction pipe. A pump left in an unheated house over the winter naturally needs to be drained.

Structurally, surface pumps can be centrifugal or vortex. Vortex pumps are more compact and capable of generating significantly greater pressure than centrifugal pumps with similar impeller sizes. However, their actual parameters depend on the quality of assembly and the manufacturing accuracy of the working parts, since the creation of vortices between the blades of the impeller is a delicate matter and depends on the size of the gaps between the vortex blades and the flow part. For the same reason, they are much more sensitive than centrifugal ones to the abrasive action of solid particles, which wear out working surfaces over time. Therefore, vortex pumps are only suitable for pumping very clean water. In addition, when operating, the vortex pump produces unpleasant high-frequency howling sounds.

More reliable suction at shallow depths (up to 9 meters) is provided by pumps with a built-in ejector. The effect is achieved by creating a vacuum area at the pump inlet. For example, they work on this principle. The body and impeller of this centrifugal ejector pump are made of stainless steel. This ensures their durability and abrasive resistance to sand and suspended matter contained in water.

To supply water from deeper wells, as well as shallow wells drilled to sandy horizons, can be used. The main pump is usually installed in the house. This reduces the chance of it being stolen, as often happens with surface pumps installed in sheds and sheds, or with submersible pumps (unless the wellhead is in the basement of the house).

The pump is connected to a remote ejector by two pipes, through one of which the pumped water rises, and through the other, part of the raised water flows down to the ejector to create a suction effect. Theoretically, such pumps are capable of lifting water from depths of up to 50 meters. But the sharp drop in efficiency with increasing suction depth makes such their use impractical. In addition, submersible ejector pumps fail if air gets inside the system.

Water can also be pumped out from a well using submersible well pumps. These centrifugal pumps are similar to drainage pumps used for pumping out domestic wastewater, but unlike them they have lower capacity and significantly higher pressure. In addition, they are only capable of pumping relatively clean water. It is important that these pumps create a minimum of vibrations during operation and do not agitate the water in the well or borehole. When the pump vibrates strongly, firstly, water with a large amount of suspended particles of silt and sand enters the house, and secondly, the water source itself deteriorates: the well quickly silts up and the well breaks.

A pump for country houses and farms requires a considerable amount of electricity, and watering costs a pretty penny. It turns out that if you use your brain, this problem is completely solvable. Chelyabinsk scientists have put... a pendulum at the service of irrigated agriculture.

• 
• 

Using the power of flowing water, gravity and inertia, it can work as a propulsion device in a wide variety of areas of the agro-industrial complex. How to teach a pendulum to become a “pulling force” of the agricultural industry? This is our conversation with the author of the know-how, senior lecturer at SUSU Vadim Bakunin.

Pendulum motor

- How did the idea to create a pendulum engine come about?

It originally belongs to the Serbian inventor Veljko Milkovic. He invented a double pendulum that drives a pump, a forging press, an impact tool... The essence of the know-how is that a swinging pendulum acts on its swing axis with a variable load. She swings the slide and does useful work. Moreover, compared to a simple Archimedean lever with the same dimensions, the force impulse increases several times!

Taking this idea as a basis, we developed an algorithm for calculating the optimal parameters of a pendulum motor. Our mathematical model allows us to create a design that operates with maximum efficiency. For example, we simulated the operation of such a pendulum as a drive for a pump, and the results are encouraging. A permanent magnet creates a field that changes the polarity of the pump booster.

- Will there be a continuation?

Using a similar principle, we came up with a so-called drive pump with an unbalanced rotor, which can be a good helper for our vegetable growers. This is also a pendulum, only of the rotational type. A patent has been received for this invention. However, alternative energy sources can also be used when the wheel is driven by the force of wind or falling water. And if you make a wheel in the form of a bucket turbine, then even when the electric motor is turned off, the pump will pump water due to the so-called hydraulic feedback. As a result, uninterrupted watering and significant energy savings.

- Can this principle be used in a variety of areas?

Inertial propulsion, for example, has a reason to be used in vehicles. At one time, Veljko Milkovic designed a self-propelled cart that travels due to the work of a pendulum! And no emissions, no environmental pollution! SUSUGAU professor Gennady Kruglov became interested in this idea; he proposed using this principle to design an environmentally friendly car engine of a completely new type, devoid of the disadvantages of gasoline engines.

Hydraulic ram

- Is it possible to apply your know-how in dams for irrigating crops?

To do this, we have developed a so-called hydraulic ram, which works as if on its own; the energy supply is the flowing water itself. Its design is based on the principle of water hammer, discovered at the end of the 18th century by the inventor of the hot air balloon, Jacques-Etienne Montgolfier. If the liquid is stopped abruptly, a pressure surge will occur, which can lead to breakdowns in the pipes. But this effect can also bring considerable benefits. In 1968, Soviet physicist V. Hovsepyan finalized the algorithm for calculating the hydraulic ram, but did not take into account the inertia of the shock valve.
I came up with a way to maintain the maximum possible performance of a hydraulic ram at a variable input pressure. This makes it possible for the consumer not to have to reconfigure the hydraulic ram, but to immediately use it at any drop in water. The hydraulic ram converts shock pressure into constant pressure, providing irrigation systems with water. To do this, you don’t even need pumping with an electric motor, the water pumps itself!

Water will flow uphill!

- Is it possible to use water hammer if there is no dam or slope?

A 4,000-year-old plumbing system was discovered in the palace of the king of Knossos on Crete. Through it, water rose without a pump from the valley to the top of the mountain on which the palace stood! All terracotta pipes had a conical shape - they tapered at one end. Water was injected from the narrowed end of the pipe into the next pipe - we know this from the pneumatic loading nozzle. This created a reduced pressure in the next pipe, which impulsively sucked water forward and up the mountain. Ancient Egyptian hydraulics could also lift water without a pump to high mountain peaks.

- What can you come up with if there is no flow of water, for example, in a lake?

In 2005, experiments with water hammer in stagnant water began in Spain. Foreign scientists are using the resonance effect in the shock tube, and the first developments of a resonant hydraulic ram have already appeared. It is known that when soldiers walk in step on a wooden bridge, there is a danger that it may collapse, since the energy of their steps resonates with the structure of the material - so the officer commands “to walk at random.” But this destructive energy can be converted into useful work, such as pumping water from a pond. But I plan to go further - to use this principle to create an underwater hydraulic ram. One of the proposals is to use it to pump water out of damaged ships.

Maelstrom from the stream

- Do you have any inventions, so to speak, at the intersection of these know-hows?

We received a patent for a water pressure converter in a turbine-pump system. It, like a hydraulic ram, converts a lower pressure into a larger one, but with a higher efficiency due to the optimal designs of the components. A high-speed turbine paired with a low-speed pump is capable of delivering high-pressure water to a height greater than its level at the dam inlet! We remove unnecessary parts - the generator and electric motor, and the pressure converter pumps water without any costs, only using water energy. The result is significant savings, which is very important for farmers.

- What if there is gas instead of liquid? For example, in the wheels of a car...

Physical laws apply to both liquids and gases. For example, as part of a creative team of scientists at SUSU, headed by Candidate of Technical Sciences Irina Starunova, I calculated the overturning moment and automatic pumping of gas in the tractor wheels to give it stability even when climbing uphill. To prevent it from tipping over on a slope, you need to reduce the pressure in the front wheels and pump some of the gas to the rear. We compiled a mathematical model of movement under these conditions and coped with this task. And most importantly, modernization can prevent accidents and save people’s lives and health.

- What other similar know-how do you have?

We have patented our development of combining a hydraulic ram and a siphon, so to speak, in one bottle. A hydraulic ram works on differences in water levels, but how can you do it without laying a pipe through the body of the dam? We found a solution - we threw a siphon pipe through it. To start it, a special device creates an initial excess pressure at the inlet, and then the water flows by gravity.

Perpetuum mobile?

- It seems that a perpetual motion machine is already on the way...

We do not invent perpetuum mobile, but use the laws of physics - gravity, the water cycle in nature... True, we strive to increase efficiency, which is quite realistic. For example, recently Ukrainian inventor Andrei Ermola designed a generator that operates on the gravity of a load and the effect of the top of Sofia Kovalevskaya (she compiled the equation of its motion). When exposed to the axis, the top seems to lose orientation - it begins to “dance in circles.” This phenomenon, called eccentricity, occurs due to imbalance. Andrei Ermola claims that the “handle of the top” in such conditions rises up on its own, doing work. At first glance, this is impossible, since it contradicts our ideas about the conservation of energy. After all, this can happen if a perpetual motion machine still exists!

- How can you explain this? And use it for the benefit of humanity...

In my opinion, this is due to the resonance effect. This can happen if the system is not closed, but is somehow connected with gravity and the influence of resonance. If this is true, then in the future it may be possible to create pumps and forging presses that will work on their own! I would like to conduct research and create a mathematical model of this phenomenon. I believe that someday we will be able to subjugate the seemingly inexplicable forces of nature and put them at the service of man.
